CCDN is the last common channel register in all OMAP4 versions. Use cpu_is_omap44xx() instead of the cpu_is_omap4430(). cpu_is_omap4430() returns 0 unconditionally. This causes that the dma_common_ch_end register variable is not configured correctly on OMAP4, not even for OMAP4430. Because of this, registers between CCFN - CCDN will be not cleard in the omap2_clear_dma function in OMAP4.
